Description

Technical Field

[0001] This utility model relates to the field of tire repair tools, and in particular to a portable tire trimming tool installer. Background Technology

[0002] The tire bead insert on a forklift tire typically refers to the steel wire bead insert at the tire bead area. It is installed on the outside of the steel wire bead and connected to the bead wrapping fabric, directly contacting the rim edge when the tire is mounted on the rim. Its main function is to secure the steel wire bead, preventing displacement or loosening and ensuring tire structural stability; it also provides a tight fit with the rim, sealing against air leakage; and it effectively transfers the load borne by the tire to the rim during forklift operation, ensuring smooth and safe vehicle operation. A tire bead installer is a tool specifically designed for installing tire bead inserts on forklift tires. Its function is to accurately and efficiently install the insert onto the outside of the steel wire bead on the tire bead, ensuring a secure and accurate installation, thereby guaranteeing the proper installation and performance of the tire.

[0003] A tire bead installer typically consists of a handle, a pressure head, a guide device, and a fixing device. Its working principle involves applying external force through the handle, causing the pressure head, guided by the guide device, to accurately push and engage the tire bead with the outer edge of the tire's bead wire. The fixing device ensures the relative position of the tire bead and the tire remains fixed during installation, thus achieving fast and accurate installation of the tire bead and guaranteeing the tire's sealing and structural stability.

[0004] In existing technologies, tires and gaskets harden with age, and the internal structure of tires is dense, making it difficult to install tire strips manually. This increases the workload of installation, causes operator fatigue, affects work efficiency and quality, and can easily lead to improper installation, causing tire failure and endangering vehicle safety. Therefore, a portable tire strip installer is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable pressure strip installer, which aims to improve the problem that some installers in the prior art are difficult to install pressure strips directly by manpower.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable pressure strip installer includes two seamless steel pipes, one end of which is fixedly connected to three contact blocks, and the other end of which is fixedly connected to a sleeve. The sleeve is internally threaded with screws, and one of the seamless steel pipes is fixedly connected to the outer wall of a telescopic mechanism.

[0008] The telescopic mechanism includes a sleeve, one end of which is fixedly connected to the outer wall of one of the seamless steel pipes, and the other end of which is detachably connected to the inner wall of a square tube. The other end of the sleeve is fixedly connected to a welded collar by welding, and the other end of the square tube is fixedly connected to the outer wall of another seamless steel pipe. A tensioning component is fixedly connected to the inner wall of the sleeve, a locking component is slidably connected to the inner wall of the sleeve, and a safety component is detachably connected to the outside of the sleeve.

[0009] As a further description of the above technical solution:

[0010] The tensioning assembly includes a steel compression spring, one end of which is fixedly connected to the inner wall of the sleeve, and the other end of which is fixedly connected to a push plate.

[0011] As a further description of the above technical solution:

[0012] The locking assembly includes a slider, the outer wall of which is slidably connected to the inner wall of the sleeve, a fixing post is fixedly connected to the outer wall of the sleeve, and a set screw is threaded into the inner part of the fixing post, with one end of the set screw contacting the outer wall of the slider.

[0013] As a further description of the above technical solution:

[0014] The safety component includes a locking pin, the outer wall of which is detachably connected to the inside of the sleeve. Both the sleeve and the square tube have insertion holes inside, and the outer wall of the locking pin is detachably connected to the inside of the insertion holes.

[0015] As a further description of the above technical solution:

[0016] The top of both the screw and the set screw is fixedly connected to a nut, and the multiple nuts are of the same size;

[0017] As a further description of the above technical solution:

[0018] The outer wall of the push plate is slidably connected to the inner wall of the sleeve, and the other outer wall of the push plate is fixedly connected to one end of the square tube by a mounting nail;

[0019] As a further description of the above technical solution:

[0020] The outer wall of the slider is provided with a rough surface, and the rough surface of the slider is in contact with the outer wall of the square tube;

[0021] As a further description of the above technical solution:

[0022] The square tube has mating grooves on both sides, and the sleeve has a mating pin detachably connected inside. The outer wall of the mating pin is slidably connected inside the mating groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the installer is placed at the tire bead, and the seamless steel tube is pressed to shrink the square tube and sleeve. The steel compression spring is compressed, and after the external force is removed, the steel compression spring rebounds. The push plate pushes the square tube to move outward inside the sleeve, increasing the length of the installer so that it contacts the inner wall of the tire shell. The elasticity of the steel compression spring allows the seamless steel tube to support the tire, achieving automatic tensioning and initial fixation. Then, the set screw is rotated to press the slider, and the friction between the slider and the square tube ensures that the relative position between the square tube and the sleeve remains stable. The locking pin design ensures that even if the external force is too large, the square tube and the sleeve remain stable by inserting the locking pin. Then, the screw is rotated, and the screw rotation squeezes the rim into the tire, making it easier to install the pressure strip in the designated position. This precisely controls the degree of compression, ensuring accurate installation of the pressure strip and providing stable and uniform extrusion force, making the pressure strip installation more secure, improving installation quality and efficiency, and saving manpower.

[0025] 2. In this utility model, the excellent performance of seamless steel pipe forms a solid basic framework. The sleeve and square tube in the telescopic mechanism form a double-layer steel pipe structure. Each connection part adopts a firm fixing method, which can evenly distribute pressure when under pressure and effectively prevent the telescopic part from bending. Compared with the existing products, the structural strength is significantly improved, and it has stronger pressure and bending resistance, enabling it to withstand greater operating force to handle the removal of tire pressure strips. The locking pin and set screw tighten the square tube to enhance the rigidity of the telescopic mechanism and maintain a stable structural shape, making the entire installer less prone to bending and damage under complex stress environments.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a portable tire bead installer, comprising two seamless steel pipes 1. The seamless steel pipes 1 possess excellent compressive and bending resistance, providing a solid and reliable foundation frame for the entire installer, and fixing the entire installer to the tire bead using the two seamless steel pipes 1. Three contact blocks 2 are fixedly connected to one end of each seamless steel pipe 1. The contact blocks 2 engage with the tread pattern around the tire bead to form a mating structure, preventing slippage after the installer is installed at the tire bead. The design of the three contact blocks 2 allows for adaptation to tire bead structures with different internal structures. A sleeve 3 is fixedly connected to the other end of each seamless steel pipe 1, providing a stable support point for subsequent movement. A screw 4 is threaded inside the sleeve 3. Rotating the screw 4 causes it to move towards the tire, pressing the entire outer disc of the tire inward, thereby pushing the entire tire bead inward for installation. A telescopic mechanism is fixedly connected to the outer wall of one of the seamless steel pipes 1. The telescopic mechanism adjusts the diameter of the entire installer, facilitating stable fixing of the entire installer at the tire bead for convenient subsequent tire bead installation.

[0034] The telescopic mechanism includes a sleeve 5, one end of which is fixedly connected to the outer wall of one of the seamless steel pipes 1. The sleeve 5 is used to cooperate with the subsequent structure so that the entire installer can open and be fixed at the tire bead to facilitate the subsequent installation of the pressure strip. A square tube 6 is detachably connected to the inner wall of the other end of the sleeve 5. A welded collar 16 is fixedly connected to the other end of the sleeve 5 by welding. The welded collar 16 is used to increase the structural strength at the joint between the square tube 6 and the sleeve 5, preventing excessive stress at the joint from causing bending or breakage. The sleeve 5 and the square tube 6 form a double-layer steel pipe structure to improve the overall structural strength and prevent bending of the telescopic part due to excessive pressure during use. The square tube has a docking groove 15 on both sides. The docking groove 15 is elongated and provides a sliding track for the sliding of the subsequent structure. A docking pin 17 is detachably connected inside the sleeve 5, and the outer wall of the docking pin 17 is slidably connected inside the docking groove 15. By passing the butt pin 17 through the sleeve and into the butt groove 15 on the square tube 6, the square tube 6 can slide inside the sleeve 5, ensuring that the square tube 6 and the sleeve 5 cannot separate during relative sliding. When disassembly is needed, the butt pin 17 can be removed to separate the square tube 6 from the sleeve 5. The other end of the square tube 6 is fixedly connected to the outer wall of another seamless steel pipe 1. This allows adjustment of the distance between the two seamless steel pipes 1 by adjusting the telescopic length between the square tube 6 and the sleeve 5, thus enabling the seamless steel pipe 1 to be securely fastened inside the tire bead. A tensioning component is fixedly connected to the inner wall of the sleeve 5. This tensioning component automatically adjusts the relative position of the sleeve 5 and the square tube 6, allowing the two seamless steel pipes 1 to generate an outward thrust, thereby fixing the entire installer in the middle of the tire. A locking component is slidably connected to the inner wall of the sleeve 5. This locking component ensures the stability of the relative position of the square tube 6 and the sleeve 5 during use of the portable forklift tire pressure strip installer. The sleeve 5 has a detachable external safety component, which provides additional protection for the stable connection between the square tube 6 and the sleeve 5, ensuring that there will be no accidental unlocking under any circumstances.

[0035] The tensioning assembly includes a steel compression spring 7. One end of the steel compression spring 7 is fixedly connected to the inner wall of the sleeve 5. In its natural state, the steel compression spring 7 generates an outward thrust, which allows the entire square tube 6 and the sleeve 5 to naturally open, enabling the two seamless steel tubes 1 to support the forklift tire. The other end of the steel compression spring 7 is fixedly connected to a push plate 8. The outer wall of the push plate 8 is slidably connected to the inner wall of the sleeve 5, and the other outer wall of the push plate 8 is in contact with one end of the square tube 6. The push plate 8 is used to transmit the spring force to the square tube 6, so that when the position of the square tube 6 changes inside the sleeve 5, it can always provide an outward thrust to the square tube 6, thereby causing the two seamless steel tubes 1 to generate a certain compressive force outward, thus stably fixing the entire installer in the middle of the forklift tire. At the same time, the mounting pin 16 fixes one end of the entire square tube to prevent the square tube from accidentally detaching.

[0036] Reference Figures 2 to 4 The locking assembly includes a slider 9, whose outer wall is slidably connected to the inner wall of the sleeve 5. This allows the slider 9 to move slightly within the sleeve 5, providing a basis for subsequent clamping operations. The outer wall of the slider 9 is roughened, and this roughened surface contacts the outer wall of the square tube 6. When the square tube 6 extends or retracts to a suitable position within the sleeve 5, the slider 9 presses firmly against the square tube 6 under frictional force, preventing accidental movement of the square tube 6 due to external impact. A fixing post 10 is fixedly connected to the outer wall of the sleeve 5, providing an installation and movement foundation for subsequent structures. The fixing post 10 has an internal threaded connection to a set screw 11. One end of the set screw 11 contacts the outer wall of the slider 9. The threaded design of the set screw 11 allows it to rotate and move linearly inside the fixing post 10. This increases the pressure of the set screw 11 on the slider 9, increasing the friction between the slider 9 and the square tube 6. This friction helps the square tube 6 maintain a stable relative position with the sleeve 5. When the installer is not needed, turning the set screw 11 outward reduces the friction between the slider 9 and the square tube 6, allowing the square tube 6 to be pulled out of the sleeve 5. This facilitates disassembling the entire installer into two parts, enhancing its portability. Nuts 12 are fixedly connected to the top of both the screw 4 and the set screw 11. Multiple nuts 12 are of the same size, allowing operators to use the same tool without frequent tool changes, thus improving work efficiency.

[0037] The safety assembly includes a locking pin 14, the outer wall of which is detachably connected to the inside of the sleeve 5. Inserting the locking pin 14 fixes the position of the sleeve 5 and the square tube 6. Both the sleeve 5 and the square tube 6 have insertion holes 13 inside. The outer wall of the locking pin 14 is detachably connected to the inside of these holes. After the square tube 6 extends or retracts to the desired position and is initially fixed by the locking assembly, the locking pin 14 is inserted into the insertion hole 13, thereby connecting the square tube 6 and the sleeve 5 by increasing external prestress. When excessive external force causes friction to make it difficult to stabilize the position of the square tube 6, the locking pin 14 prevents relative displacement between the square tube 6 and the sleeve 5, providing reliable stability throughout the operation.

[0038] Working principle: When using the portable forklift tire pressure strip installer, first press one of the seamless steel pipes 1 to cause the square tube 6 and the sleeve 5 to contract, thus placing the entire installer at the tire bead. At this time, the steel compression spring 7 is in a compressed state due to the external force. When the external force is removed, the steel compression spring 7 returns to its deformation and generates a reverse elastic force, which causes the square tube 6 to move outward inside the sleeve 5 through the push plate 8, thereby increasing the length of the entire installer. This causes the two seamless steel pipes 1 to contact the inner wall of the tire shell, and the elastic force of the steel compression spring 7 enables the two seamless steel pipes 1 to support the forklift tire and maintain a stable tension, thus initially fixing the installer to the tire. After the square tube 6 is moved to the appropriate position, the screw is rotated, causing the set screw 11 to move into the sleeve 5, thereby squeezing the slider 9. The rough surface of the slider 9 generates a certain friction force on the square tube 6, and the relative position of the square tube 6 and the sleeve 5 is kept stable by the friction force. When the external force on the installer is too large and the friction force is not enough to stabilize the square tube 6, a locking pin 14 can be inserted into the insertion hole 13 where the sleeve 5 and the square tube 6 are in contact. This increases the external prestress and prevents the square tube 6 and the sleeve 5 from moving relative to each other during the use of the installer. Then, by rotating the two screws 4, the screws 4 move into the inside of the loader tire and squeeze the tire plate shell, thus facilitating the installation of the pressure strip inside the loader tire.

[0039] The seamless steel pipe 1 itself possesses excellent compressive and bending resistance, providing a solid foundation frame for the entire installer, capable of withstanding significant external forces without easily deforming. Regarding the telescopic mechanism, the sleeve 5 and the square tube 6 form a double-layer steel pipe structure, effectively enhancing the overall structural strength. When subjected to pressure during use, the double-layer steel pipe structure evenly distributes the pressure, preventing bending of the telescopic parts due to excessive localized stress. Simultaneously, all connections employ robust fixing methods, such as the fixed connection between the sleeve 5 and the seamless steel pipe 1, and the fixed connection between the square tube 6 and the seamless steel pipe 1, ensuring tight and reliable connections between components under significant tensile and compressive forces, preventing loosening or breakage. Furthermore, the operation of tightening the square tube 6 through the locking pin 14 and the set screw 11 enhances the rigidity of the entire telescopic mechanism to a certain extent, enabling it to maintain a stable structural form even under complex stress environments. This allows the entire installer to withstand significant operating forces without easily bending or being damaged. Additionally, the design of the same type of nut 12 allows operators to use the same tool, eliminating the need for frequent tool changes and improving work efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
